  • exo = divergent strabismus; eso = convergent strabismus; ## = clinically easily detectable nystagmus; # = indicates clinically detectable latent nystagmus or intermittent nystagmus; 0 = no clinically detectable nystagmus; SPI = slow phase increasing velocity waveform; SPD = slow phase decreasing velocity waveform; pend = pendular waveform; beats = less than 5 nystagmus beats per 5 seconds; + = presence of latent form of nystagmus.
